me rier ToaZl'whom it may concern: 3 p Be it known that I, JOANNY Mninnn'r, citizen of the French Republic, and residing at wlLaiz {pres Pont-de-IVeyle, in the Depart ment of Ain, France, have invented jcertain new and useful Improvements in Agricultural Machines, of which the following is a specification. a

' This invention relates to agricultural machines.

A large'number ofinotor drivenagricuL tural machines have been proposed with mechanically driven rotary plows. Such plows have usually consisted of drums furnished with variously shaped tools such as 1 disks, f claws, picks, cutters, bladesyetcg All those plows are intended to work a given condition of soil in-such manner as topro duce' a characteristic structure or granula tion determined by the lparticular shape of thentools used. For alteringthe size "of the granulation according to the composition of the soils to be lightened or the rnatiir e of the crops to =be cultivated; two "means "have hith erto' beenemployed. The "first consists in vanying the distance of the tools from one sists invarying the speed of rotation. The

a "first mean-s is not suitable for all cases even when} the tools have been constructed to al low of their being spaced farthenapart it is i1 s1ial1 y tedions and laborious and often cannot be accornplished by one ma n falone. The-*zcther means which consists in varying thespeed ot-rotation would be inorepractical} if thespeed of rotationcould be varied infinitely." Now -nnless the speed-changing mechanism is A rendered extremely coinpli cate'd Ka condition whiclris prohibitive in the construction of; agricultural Inachinery) it is scarcely practicable"tofprovideinore than two or threechang'es which is wholly inadequate inmost cases; p

It is one-time ohjctsof the present invention 'to provide means *for combining the speed of rotation of the plowing apparatus with the speed of travelof the motor vehicle carrying the said apparatus. In this mannerit is then possible to obtain as regards the range or path of the tools, a kinematic variation thatis infinitely greater than in the known machines and therefore to 'pro'duce a variety 'of granulation ranging from "a large clod to' fi'ne powder according AGRICULTURAL mricriinn.

sists essentially of a mot ployed for {many purposes such a tractor, or as vehfcle carrying tools for various piirpos's. 4 is a road locomotive,

a casing inclosing a first-speed change gear with reverse driving mechanism. In Fig. 2 the gear Wheels (shown in dotted lines) allow of two different speeds according to whether the gears are engaged at A or B. From this speed change gear there extends rearwardly a driving shaft 5 having a fast bevel pinion 6 that engages with the bevel wheel 7 fast on the cross shaft 8. This shaft also carries the two pinions 9 and 9 adapted to engage alternatively the wheels 1.0,and .10 whichpermit .a change of speed of the counter-shaft 11 according as they are engaged at C or at D.

The control of both these speed change gears is effected by any suitable means.

The shaft 11 carries on its other end a fast pinion 12 engaging the toothed gear 13. mounted fast on the hub 1d of the driving wheel 15 whichlatter is of comparatively large diameter. When the machine .is used for drawing a plow the driving wheel runs in the open furrow that has been formed by theprevious passage of the machine and since its tread is then furnished with spikes or bars these penetrate into the sub-soil which gives a firmer hold than the overlying layer of arable soil. Moreover, the spikes orbars effect the breaking up of the top crust of the sub-soil layer that v is formed-by the frequent passage of cultivating implements.

As shown in Fig. 2 the axis of the hub 14: of the driving wheel is ofiset from the axis of the shaft 8 to permit of the power for driving the plow being transmitted ,through the axis of the opposite wheel 18.

The inner end of the axle 16 carries a bracket 17 that serves as a bearing for the journal 19 of the supporting wheel 18. This wheel is -mounted as follows: Revolubly mounted on the bracket 17 is a disk 20 arranged eccentrically to the journal member 19.v This disk 20 has a peripheral race for the rollers 21on which the hub 22 of the wheel 18 turns. The bracket 17 is adapted to be shifted along the axle l6 and fixed to the latter by means of bolts extending through. one or other of a choice of holes 23 so that the gage of the machine may be altered to suit requirements. By operating ,the' lever 24 (Fig. 3) rigidly fastened to circumstances of use. As best shown in Fig. 2 the axle 8 has an extensible joint 8 and, the linkconnecting the levers 24and 25 is extensible to permit the lateral adjustments of the-wheel 18. The journal 19 r is hollow and is traversed by the revoluble shaft 8. journaled in the ball bearing 26 fixeclfito the journal 19. The end of the shaft 8 carries a sprocket wheel 27 that from the seat 29. The steering wheel rotates in approximately the same plane as the driving wheel so that the machine is adapted to turn in a very short radius backward and forward and can thus execute ever kind of agricultural work. 31 is a driving pulley to which other machines can be coupled. It is keyed on a driving shaft 32.

The tilling-apparatus proper is pivoted to the carriage on the axis of the shaft 8 by means of two arms 33. It can be raised and lowered by any suitable means (not shown). The two arms 33 are provided at their outer ends with bearings 3st in which an axle 35 revolves. The axle receives its motion through a chain on the pinion 27. The axle 35 consists of a. cast metal core with threads 36 (Fig. 6) some centimeters in height upon which are mounted the working screw threads 37 which constitute the tools proper.- To facilitate mounting these threads are built up, of helicoidal sections connected together by means of plates 38, all the parts-being fixed by means of bolts or rivets. The outer edges of the screw threads are so shaped as to form saw teeth as shown at 39 in order to prevent grass and straw from getting between the sections. The soil is cut up by the outer edges of the threads the peripheral speed of which is greater than that of the driving wheel of the toolcarrying section of the vehicle. The strips of soil that are out are turned over by the concave surfaces of the threads in combination with the suitable ratio, between the speed of rotation of the tools and the speed of advance of the machine. When the operator alters this ratio the working is altered correspondingly. The first speed change gear which is inclosed in the gear case 4 acts at the same time upon the speed of rotation of the apparatus as a whole relatively to the speed of the motor. The second speed change gear consisting of the gears 9, 10' and 9, 10 modifies the speed ratio between the driving wheel and the tilling implement or rotary'plow.

If as shown in the drawing, each speed change gear has two speeds, then, for instance, the following ratios can be obtained between the speed of advance and the speed of rotation of the tools This represents a working which varies from a thin slice to a wide strip, or in other 1,38%, MB 1 l terms from fine granulation,

Having now described my invention what I claim as new and desire to secure by Letters Patent is: c
